FR4 ثنائي الفينيل متعدد الكلور مقابل FR4 عالي التوتر: ما الفرق؟
FR4 is the most widely used PCB substrate material, but in applications with higher operating temperatures, designers often choose high-Tg FR4 laminates. High-Tg materials provide better thermal stability and improved reliability during soldering and long-term operation. This article explains the differences between standard FR4 and high-Tg FR4, including material properties, thermal performance, and typical use cases.
